                                 Object obj)

  - ### Method Detail

    - #### initialize

          public void initialize()

      Description copied from interface: `MetaClass`
      Complete the initialisation process. After this method is called no methods should be added to the meta class. Invocation of methods or access to fields/properties is forbidden unless this method is called. This method should contain any initialisation code, taking a longer time to complete. An example is the creation of the Reflector. It is suggested to synchronize this method.
      Specified by:
        `initialize` in interface `MetaClass`
      Overrides:
        `initialize` in class `DelegatingMetaClass`

    - #### replaceDelegate

          public GroovyObject replaceDelegate()

    - #### invokeMethod

          public Object invokeMethod​(String name,
                                     Object args)

      Description copied from interface: `GroovyObject`
      Invokes the given method.
      Specified by:
        `invokeMethod` in interface `GroovyObject`
      Overrides:
        `invokeMethod` in class `DelegatingMetaClass`
      Parameters:
        `name` - the name of the method to call
        `args` - the arguments to use for the method call
      Returns:
        the result of invoking the method

    - #### getProperty

          public Object getProperty​(String property)

      Description copied from interface: `GroovyObject`
      Retrieves a property value.
      Specified by:
        `getProperty` in interface `GroovyObject`
      Overrides:
        `getProperty` in class `DelegatingMetaClass`
      Parameters:
        `property` - the name of the property of interest
      Returns:
        the given property

    - #### setProperty

          public void setProperty​(String property,
                                  Object newValue)

      Description copied from interface: `GroovyObject`
      Sets the given property to the new value.
      Specified by:

      Overrides:
        `setProperty` in class `DelegatingMetaClass`
      Parameters:
        `property` - the name of the property of interest
        `newValue` - the new value for the property

    - #### addNewInstanceMethod

          public void addNewInstanceMethod​(Method method)

      Description copied from interface: `MutableMetaClass`
      adds a new instance method to this MetaClass. Instance methods are able to overwrite the original methods of the class. Calling this method should not be done after initialise was called.
      Specified by:

      Overrides:
        `addNewInstanceMethod` in class `DelegatingMetaClass`
      Parameters:

    - #### addNewStaticMethod

          public void addNewStaticMethod​(Method method)

      Description copied from interface: `MutableMetaClass`
